SCEA's revealed that a studio other than 2Ks Boston, Australia and Marin is working on the PS3 version of Bioshock in this US PlayStation Blog post.
"Because this is the first PS3 title from 2K Marin, 2K Australia and 2K Boston, we’ve also got another development partner with some outstanding PS3-specific coding chops helping out with the project," said a spokesperson. "We can’t talk about what studio that is yet, but we look forward to revealing that in the future."
The piece also confirms that there are "as-yet-unannounced components" to the new version, but, obviously, doesn't hint as to what they are. Multiplay, please.
Take a look. Thanks, Blerk.
